API responses

• Explain that WebEngine can serve structured responses as well as HTML pages.
• Explain the benefit of one routing model for both page and API endpoints.

HTML pages vs API endpoints

• Explain the separate directories or conventions used for APIs.
• Explain how content negotiation and response type affect routing.

What API logic looks like

• Explain similarities to page logic.
• Explain what changes when the response is data rather than a document.
• Explain the JSONDocument vs HTMLDocument.
• Typically there's no need to write API logic for background updates to the page: server-side rendering can be made into a fluid user interface without the use of API page updates.
